Eminem took to Twitter earlier today to announce 10 years of sobriety, posting a photo holding his Alcoholic Anonymous coin.

The rapper has battled with addiction of prescription medication since the early 2000s. During his worst days, he revealed he was taking up to 60 Valium and 30 Vicodin a day. In 2007, Eminem was admitted to hospital after an almost fatal drug overdose.

“The doctors told me I’d done the equivalent of four bags of heroin, they said I was about two hours from dying”. He also opened up about the weight gain he experienced during those time, “I was close to 230 pounds. I’m not sure how I got so big, but I have ideas. The coating on the Vicodin and the Valium I’d been taking for years leaves a hole in your stomach, so to avoid a stomachache, I was constantly eating — and eating badly.”

It was after this overdoes, Eminem had decided to get clean, checking himself into a rehab clinic. With the help of Alcoholic Anonymous, the rapper began the 12-step program, an was clean by 2008.

Eminem said he figured out a way to stay clean by focusing on exercise. “When I got out of rehab, I needed to lose weight, but I also needed to figure out a way to function sober,” he added. “Unless I was blitzed out of my mind, I had trouble sleeping. So I started running. It gave me a natural endorphin high, but it also helped me sleep, so it was perfect. It’s easy to understand how people replace addiction with exercise. One addiction for another but one that’s good for them.”

In 2013, he opened up about his drug addictions to the world in a documentary, ‘How To Make Money Selling Drugs’, not only a re-telling of his experiences, but about the whole dealing world. “I don’t know at what point exactly it started to be a problem. I just remember liking it more and more,” explains Eminem in the film.

During this milestone, Eminem was also seen on the stage of Coachella, featuring artists including, 50 Cent and Skylar Grey.
